Opis:: Statistical properties of the hyperchaotic Qi system are studied. The theory, recently formulated and applied for the damped driven pendulum, is used in this investigation. Asymmetry coefficients, related to the statistical moments of distributions composed from the time-series, are shown to behave in a different way for periodic, chaotic and hyperchaotic solutions and are proposed as indicators of chaos and hyperchaos.

Opis:: The organic-inorganic hybrid salt: 1,1'-methylenedipyridinium pentacynidonitrosoferrate(II)pentahydrate is synthesized and characterized by multinuclear NMR, IR, and UV-vis spectroscopies and elemental analysis. The third order nonlinear optical properties of the new complex in an aqueous solution have been studied using Z-scan technique. Measurements were performed for input intensities (I₀) of 437 and 241 W/cm² for the two concentrations with a CW diode laser at 635 nm wavelength. The nonlinear optical absorption coefficient (β) and nonlinear refraction (n₂) are found at 1.28×10¯³ cm/W and 10.17×10¯⁹ cm²/W, respectively. The overall results suggested that better nonlinearity was observed at a higher concentration of sample. Our results suggest that this material is considered as a promising candidate for future optical device applications.

Opis:: Charging operations of a compact Tesla transformer were experimentally investigated, in single-shot and rep-rate (50 pps for 1 s) modes, respectively. The charging limitations were also explored. The experimental results were compared and analyzed. The maximum secondary charging voltages of the Tesla transformer were measured to be 380 kV and 300 kV in single-shot and rep-rate modes, respectively. The RMS pulse-to-pulse instability of the secondary charging voltage is generally less than 10% but increases with the increasing initial voltage across the primary capacitor. Since the secondary capacitor of the Tesla transformer is a pulse forming line (PFL), continued operation is possible if there is breakdown in the PFL. Furthermore, operation can even be continued under occasional breakdown for some pulses, without the effects on the operations of subsequent pulses.
